似乎没必要用结构体（？
```
// LG-P1413.cpp
#include <bits/stdc++.h>
using namespace std;
int maxn[10],zom[10][500000];
int main()
{
int n,t,p,tot = 0;
cin >> n;
for(int i = 1;i <= n;i ++)
{
cin >> p >> t;
maxn[p] = max(maxn[p],t);
zom[p][t] ++;
}
for(int i = 1;i <= 6;i ++)
{
for(int j = 1;j <= maxn[i];)
{
if(zom[i][j])
{
tot ++;
j += 60;
}
else
j ++;
}
}
cout << tot;
}
```
